USES=xfce: Stop overriding MASTER_SITE_SUBDIR.
Add an XFCE SITE_SUBDIR abbreviation and use it forf or the xfce ports,
which removes the need to set MASTER_SITE_SUBDIR in any of them.
This fixes ports that have USES=xfce but do not use the XFCE MASTER_SITE,
namely sysutils/xfce4-bsdcpufreq-plugin.

Replace USES=libtool:oldver with USES=libtool or USES=libtool:keepla in
the 32 ports that still use it. Bump PORTREVISION on their dependent
ports except the ones that depend on these:
audio/libogg
audio/libvorbis
devel/pcre
ftp/curl
graphics/jpeg
graphics/libart_lgpl
graphics/tiff
textproc/expat2
textproc/libxslt
In these cases the same trick as in the recent gettext update is used.

Remove USE_CDRTOOLS from bsd.port.mk
This macros has been useless since cdrtools-cjk port has gone.
This macros also lead to badly handled dependencies assuming that the dependency
on cdrtools was most BUILD and RUN dependency. While most of the time it is
simply a RUN dependency and sometime a build one.
While here:
- Trim some headers
- Convert some ports to optionsng
- Convert some ports to USES= gettext

new devel/pkgconf added to replace devel/pkg-config. new version of pkg-config
are no more self hosting so we are stuck with 0.25 version while pkgconf provide
the same set of features as 0.27 and a compatible frontend. A symlink to
pkg-config has been added for convenience and compatibility
This also introduces a new macro to use pkgconf in your ports:
USE_PKGCONFIG
it can take the following arguments:
- yes (meaning build only dep)
- build (meaning build only dep)
- run (meaning run only dep)
- both (meaning run and build dep)
From now USE_GNOME= pkgconfig is deprecated in favour of USE_PKGCONFIG
The old gnome macro has been modified to use pkgconf but still the sameway: run
and build dep to avoid large breakage.
While here fix some ports relying on pkg-config but not specifying it, fix some
ports broken because testing wrong .pc files, and fix ports using pkg-config
--version to determine pkg-config version instead of
pkg-config --modversion pkg-config like recommanded by pkg-config
